The grandmaster’s account of his 1997 battle with Deep Blue is both thrilling and thoughtful

Garry Kasparov is arguably the greatest chess player of all time. From 1986 until his retirement in 2005, he was ranked world No 1. He is also a leading human rights activist and is probably close to the top of Vladimir Putin’s hitlist, not least because he tried to run against him for the Russian presidency in 2007. But for people who are interested only in technology, Kasparov is probably best known as the first world champion to be beaten by a machine. In 1997, in a famous six-game match with the IBM supercomputer Deep Blue, he lost 3½-2½.

In the grand scheme of things, losing by one game in a six-game match might not seem much, but at the time it was seen as a major milestone in the long march towards “artificial” intelligence (AI). With the 20/20 vision of hindsight we can view it in a less apocalyptic light: the triumph of Deep Blue was really a victory of brute computing power, clever programming and the ruthless determination of a huge but struggling corporation to exploit the PR advantages of having one of its products do something that would impress the world’s media. But if you believe that AI has something to do with cognition, then Kasparov’s epochal defeat looks like a sideshow.

Kasparov is not a good loser; the resulting media coverage didn’t do him any favours and IBM scooped the PR jackpot
